Step-by-step explanation:

1/3

Answer 2

The required value of a is 1/3 for parabola [tex]y = 1/3x^2[/tex].

A parabolic dish with vertex (0,0) at the center, width is 6 inches and depth is 3 inches. y = ax² where a is to be determined.


What is a parabola?

A parabola is a cross-section cut out of the cone and represented by an equation [tex]y=4ax^2[/tex].

Here,  
Vertex is at the center of the parabolic plate (0,0),
with the help of the width and depth coordinate of the one corner is(3,3).
Now put these coordinates in y = ax²  
3 = a3²
a = 3/3²
a = 1/3

Thus, The required value of a is 1/3 for the parabola [tex]y = 1/3x^2[/tex].

Answers

Answer:

  13 units

Step-by-step explanation:

The distance is found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((14 -2)² +(6 -1)²) = √(144 +25) = 13

The distance between the two points is 13 units.

Consider a system with sampling rate 52,500 samples per second.
(a) Determinethe maximum frequency of the pre-sampled signal if the system utilizes 18% oversampling.
(b) Determine the percentage oversampling if the maximum frequency from part (a) isincreased by 10%.

Answers

Answer:

The answer is "[tex]22,246 \ H_z \ \ and \ \ 7.3\%[/tex]"

Step-by-step explanation:

The sampling rate: [tex](f_s) = 52,500 \ \frac{samples}{sec}[/tex]

In point a:

The sample signal frequency = f  

They recognize that the id [tex]\geq[/tex] 2f sampling frequency could be returned to its original signal unless the aliase effect is detected elsewhere,  Yet under percentage =18%

[tex]\ sampling \ rate = 2 \times 1.18 \times f[/tex]

[tex]\to f = \frac{52,500}{2 \times 1.18}\\\\[/tex]

       [tex]= 22,246 \ h_z[/tex]

In point b:

Maximum 22,242 frequency is increased by [tex]10 \ \%[/tex]

[tex]f_a =22,246 \times 1.1[/tex]

    [tex]= 24,470.6\\\\=24,471[/tex]

[tex]\ sampling \ rate= x \times 2 \times 24,2471 \\[/tex]

                    [tex]x= \frac{52,500}{48,942} \\\\x= 1.073\\\\[/tex]

over sampling percentage [tex]= 7.3 \ \%[/tex]

Find the slope of the line that passes through the points (1,-4) and (3, -1).

Answer:

Step-by-step explanation:

Solve the following system of equations. x + y + 8z = 16
2x + 7z = 19
4x - 4y + 4z = 4

a. x = 1,y = 2,z = 2
b. x= 2,y = 2,z = 1
c. x = 6,y = 2,z = 1
d. x = 13,y = 11,z = -1​

Answers

By substitution, we will see that the solution of the system is:

x = 13, y = 11, z = -1

The correct option is D.

How to solve the system of equations?

Here we have a system of 3 equations:

x + y + 8z = 16

2x + 7z = 19

4x - 4y + 4z = 4

I will solve it by substitution, first, let's simplify the equations. Here we can divide the third equation by 4 so we remove all the common factors, then the system becomes:

x + y + 8z = 16

2x + 7z = 19

x - y + z = 1

Now, I will isolate x on the second equation:

x = (19 - 7z)/2 = (19/2) - (7/2)*z = 9.5 - 3.5*z

Now we can replace that on the other two equations:

(9.5 - 3.5*z) + y + 8z = 16

(9.5 - 3.5*z) - y + z = 1

Rewriting the system we get:

y + 4.5z = 6.5

-y - 2.5z = -8.5

Now we can isolate y on the first equation:

y = 6.5 - 4.5z

Replacing that on the other equation we get:

-(  6.5 - 4.5z) - 2.5z = -8.5

-6.5 + 4.5z - 2.5z = -8.5

2z = -8.5 + 6.5 = -2

z = -2/2 = -1

Then the value of y is:

y = 6.5 - 4.5z = 6.5 - 4.5*(-1) = 11

And the value of x is:

x = 9.5 - 3.5*z = 9.5 - 3.5*(-1) = 13

So the solution of the system is:

x = 13, y = 11, z = -1

The correct option is D.

Using a system of equations, it is found that Stefan won 7 games.

In our system, we have that:

x is the number of games Marion won.y is the number of games Stefan won.

Marion won five times the difference between the number of games Stefan won and the number four, hence:

[tex]x = 5(y - 4)[/tex]

Marion won 15 games, hence [tex]x = 15[/tex], and:

[tex]15 = 5(y - 4)[/tex]

[tex]y - 4 = 3[/tex]

a. 2.45
B. 4.6
C. 7.05
D. -1.88

Answers

B.4.6
I divided 276/60 and got b

The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).

What is Z -score?

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

Given the average cost to rent a car for a week is $276

And the standard deviation is $60

To determine the Z-score for a weekly rental of $423.00

Here,

ц = 276

σ = 60

X = 423

⇒ z-score = (X-ц )/σ

Substitute the values,

⇒ z-score =  (423 - 276)/60

⇒ z-score = 147/60

⇒ z-score = 2.45

Hence, the z-score for a weekly rental is 2.45.

Graphically solve a system of equations in order to determine the number of cookies, x,x, and the number of brownies, y,y, that Jace bought.

Answers

Answer:

(9, 18) (3, 6) Plz correct me if wrong

Step-by-step explanation:

Jace bought 4 cookies and 2 brownies from the bakery.

Let x represent the number of cookies and y represent the number of brownies.

Since he bought $9 worth of cookies and brownies. Each cookie costs $0.75 and each brownie costs $3. hence:

0.75x + 3y = 9      (1)

Also, he bought twice as many cookies as brownies, hence:

x = 2y

x - 2y = 0     (2)

Solving equation 1 and 2 simultaneously gives x = 4, y = 2
